What will be limiting the ability of EOS witness nodes to oversell their resources ? Network capacity benchmarks ?
In the context of STEEM,
If 20 nodes all with an average capacity of 30 000 Tx/s set their blocksize limit to something that would equate 300 000 tx/s if 100% of SP was being used to fill blocks.
If 30% of steem is in STEEM Power, and 5-10% of SP is ever being used at once. It mean witness have a temptation to oversell their resources by 20-50 times.
It could be disruptive to some dapp business models if they were promised a stable or even ever increasing network capacity but being early and alone on the network, were being over-delivered bandwidth relative to the number of EOS tokens they hold.
